Causes of Global Warming: the Human impact Both natural and human factors contribute to global warming, however, evidence 3 has shown that the warming we are currently witnessing is largely as a result of human forcing. According to the Union of Concerned Scientists 4, there are several indications that provide evidence that humans are the cause of global warming rather than it being due to natural variability – these indicators include: Warming Oceans. Oceans have absorbed 20 times more heat than the atmosphere resulting in warmer oceans 5, 6.

Global Warming Effects and Causes: A Top 10 List Global Warming Effects and Causes: A Top 10 List. One of the biggest issues facing us right now is global warming. Its effects on animals and on agriculture are indeed frightening, and the effects on the human population are even scarier. The facts about global warming are often debated in politics and the media, but, unfortunately, even if we disagree about the causes, global warming effects are real, global, and measurable. The causes are mainly from us, the human race, and the effects on us will be severe.

Human vs. Natural Contributions to Global Warming Human vs. Natural Contributions to Global Warming. The percentage contribution to global warming over the past 50-65 years is shown in two categories, human causes (left) and natural causes (right), from various peer-reviewed studies (colors). The studies used a wide range of independent methods, and provide multiple lines of evidence that humans are by far the dominant cause of recent global warming. Most studies showed that recent natural contributions have been in the cooling direction, thereby masking part of the human contribution and in some cases causing it to exceed 100% of the total warming.

Natural and Man-Made Causes of Global Warming 4. Overpopulation: Another cause of global warming is overpopulation. Since carbon dioxide contributes to global warming, the increase in population makes the problem worse because we breathe out more carbon dioxide in the atmosphere.lobal warming is affecting many parts of the world. Due to global warming, the glaciers are melting which is causing the rise in the sea level. When the level of the sea rises, it causes danger to the people living in the low lying areas.

Top 12 Main Causes of Global Warming List Before leading towards the causes, it is very much important to know what is global warming. Global warming, can be defined as an increase in the earth’s atmospheric, oceanic temperatures and an overall change in earth’s atmosphere including a rise in sea levels and variability of snow falls.Climate change and associated impacts vary from region to region around the globe.. Burning of Fossil Fuels. Each time a fossil fuel burn, carbon dioxide levels in the atmosphere increase. As we know carbon dioxide absorbs infra-red energy emitted from the earth’s surface, preventing it from returning to space.

- Net Heat Generation from Deforestation 1.1. Background Although global warming is scientifically accepted, its cause is still disputed. Nordell (2003) suggested a most natural explanation; that this warming is a result of heat emissions from the global consumption of non-renewable energy. Global warming means that heat has been accumulating in air, ground, and water since 1880.
